GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) C3VP V1
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/gpmgv/c3vp/2dvd/data101
The GPM Ground Validation Two-Dimensional Video Disdrometer (2DVD) C3VP dataset consists of snowfall data collected by the Two-Dimensional Video Disdrometer (2DVD) during the Canadian CloudSat/CALIPSO Validation Project (C3VP) field campaign.
Description
The campaign took place in southern Canada in support of multiple science missions, including the NASA GPM mission, in order to improve the modeling and remote sensing of winter precipitation.
The 2DVD measures precipitation characteristics such as size, shape, and velocity. During C3VP, there was one 2DVD instrument deployed at the Meteorological Service of Canada (MSC) operated Centre for Atmospheric Research Experiments (CARE) facility in Ontario, Canada. The data include diameter, volume, and fall speed information for individual snowflakes.
